Is a set of operations and procedures to be followed to solve a problem. The word "algorithm" comes from the latinized name of the great Arab mathematician Mohammed ibn Musa Al Rizmi Kow, who wrote about between 800 and 825 his Quitab Al Jabr Al Mugabala, which contained the system Numbering and the Hindu concept of zero. Fibonacci was, that his work translated into Latin and began with the words: Algorithm dicit. Difference between the algorithmic and computer language. Algorithmic language is one by which an analysis is carried out prior to solving the problem and finding an approach to solve it. The set of all operations to be performed and the order must be made, you will be called algorithm. The language is the one through which the algorithm is coded in a system understandable by the computer or computer. This kind of language is closer to the machine and the human being can distinguish different types depending on the proximity to the machine. It's called high-level language that is closer to human understanding and language level to those who are more understandable by the machine. Specifically, we will study a language at the border of a low level. That is why the 'C' is so powerful and fast, since the main functions are the most basic functions of the computer. Approaches to problems. The intention is to synthesize an algorithm in some way a task or calculation mechanism before being transcribed to the computer. Steps to follow are: - Prior analysis of the problem. - First view of the method of resolution. - Decomposition into modules. - (Structured Programming). - Search for partial solutions. - Final Assembly Solution
